Abstract
Iris melanomas are less likely to metastasize than ciliary body or choroidal melanomas. In order to study this difference in metastatic rate, we developed a murine model of anterior chamber (AC) and posterior compartment (PC) melanoma. Eighteen C57BL6 mice were inoculated in the AC (n = 6) or PC (n = 12) with B16F10 melanoma cells and eleven mice were inoculated in the AC (n = 3) or PC (n = 8) with Queens melanoma cells. The animals were sacrificed at 12 to 14 days post inoculation and histologically examined. Results were that 8 of 9 AC tumors and 10 of 20 PC tumors grew. One PC tumor metastasized to the lungs. This model may be used to study anterior versus posterior ocular melanoma differences.
